Seems I just had the wrong value in my retract macro… awkward

Ha! seems my signal wire was busted

My deploy marco works though the retract doesn't

deploy

M280 P3 S10 I1

retract

M280 P3 S90 I1

If I home Z it deploys, lowers and reads the height then deploys and flashes

@tomwang256:

Are you on duet 0.8.5 or duet wifi? I have BLTouch wired up with my wifi working well.
it's mostly the same instruction that W3DRK but the expansion header is not the same on the wifi so you would have to use pin 8 for Heater 3 pwm output instead.
see documentation here : https://duet3d.com/wiki/Duet_WiFi_wiring_diagrams

I am using the Duet 0.8.5

W3DRK, So I have wired up my bltouch int he way that have described but cant seem to get my duet to deploy or retract using macros or gcode.

I have the following defined in my config.g

; BLTouch
M307 H3 A-1 C-1 D-1
M558 P4 X0 Y0 Z1 H3 F200 T5000    	
G31 P200 X-4 Y40 Z2

I am running the latest stable dc42 fork of the Duet 0.8.5 firmware

Firmware Version:	1.17a (2017-01-02)
Web Interface Version:	1.14-RC1

Any ideas what to look at?

Just ordered myself a bltouch and will be adding it to my duet 0.8.5, thanks for documenting the install mate
